Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a cable fastening box for long-distance vertical continuous cable ducts on ships. Background Technology

[0002] In shipbuilding, cables for sensors such as depth sounders and logs need to be extended from the cabin to the main deck via vertical cable conduits, which are typically over 20 meters long. In existing technology, the cables are kept suspended and taut within these vertical conduits for extended periods, leading to the following problems:

[0003] (1) Cable damage: Suspended vibration accelerates the wear of the cable sheath, affecting the stability of signal transmission;

[0004] (2) Difficult to maintain: Traditional fixing methods (such as filling with mud and sand or solidifying the plug) cause the cable to become fixed to the pipe, and the entire pipe needs to be removed during maintenance, which is costly;

[0005] (3) Poor adaptability: Most existing fixing devices are rigid structures, which cannot be adapted to cables of different diameters or dynamically adjust the binding force.

[0006] A search revealed that existing cable support technologies either employ complex structures for support, leading to high maintenance costs, or have simple structures but are not designed for laying cables in long, vertical conduits. Therefore, there is an urgent need for a cable fastening box for long, continuous vertical cable ducts on ships that combines detachability, dynamic adjustment capabilities, and environmental adaptability. Summary of the Invention

[0007] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a cable fastening box for long-distance vertical continuous cable ducts on ships, so as to achieve stable cable fixing, convenient maintenance and environmental adaptability for long-distance vertical operation.

[0008] The purpose of this utility model is achieved as follows:

[0009] A cable fastening box for a long-distance vertical continuous cable duct on a ship is applied to the cable duct in the depth sounder compartment of the ship. The cable duct extends vertically from the depth sounder compartment to the main deck, and a cable fastening box is installed on the cable duct at certain intervals.

[0010] The cable fastening box includes a cable box body, a removable blind plate is provided on one side of the cable box body, and a sealing plate is provided on the other side of the cable box body; a quick-release flange is provided on the top surface of the cable box body, and the top surface of the cable box body can be quickly opened and closed by bolts;

[0011] A top cable guide tube is vertically connected above the top surface of the cable box body for guiding the cable tube into the cable box body; a bottom cable guide tube is vertically connected below the bottom surface of the cable box body for guiding the cable tube out of the cable box body.

[0012] The cable box is equipped with a cable laying bracket, and the cable laying bracket is provided with a U-shaped elastic clip.

[0013] Furthermore, a cable fastening box is installed every 3 to 5 meters on the cable conduit.

[0014] Furthermore, an upper sleeve is fitted onto the top end of the upper cable guide tube, and the opening diameter of the top surface of the upper sleeve is larger than the opening diameter of the upper cable guide tube, which facilitates the insertion of the cable tube.

[0015] Furthermore, a lower sleeve is fitted at the bottom end of the lower cable guide tube, and the bottom opening diameter of the lower sleeve is larger than the opening diameter of the lower cable guide tube, which facilitates the cable tube to pass through.

[0016] Furthermore, the cable laying bracket is U-shaped, comprising a vertical flat steel and two horizontal flat steels vertically connected to the upper and lower ends of the vertical flat steel, with the outer ends of the horizontal flat steels of the cable laying bracket fixed to the inner wall of the sealing plate.

[0017] Furthermore, a U-shaped elastic clip is provided on the vertical flat steel of the cable laying bracket.

[0018] Furthermore, the U-shaped elastic clip is covered with silicone rubber, and the inner side of the clip is provided with corrugated anti-slip texture.

[0019] Furthermore, a pressure sensor is embedded in the contact surface between the U-shaped elastic clip and the cable conduit to monitor the binding force in real time and prevent damage to the cable from excessive tightness.

[0020] Furthermore, the outer wall of the cable box is provided with an anti-corrosion coating, and the inner wall of the cable box is fitted with a damping and shock-absorbing pad.

[0021] Furthermore, the surface of the cable box is provided with a transparent observation window.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This utility model provides a cable fastening box for long-distance vertical continuous cable ducts on ships. It features a simple structure and convenient installation, facilitating quick and easy operation and long-distance cable duct retrieval. Combining a modular quick-release structure with elastic binding, it achieves for the first time "segmented fixing and independent maintenance" of ship cables, promoting widespread application. The introduction of a pressure sensor for real-time monitoring of binding force fills the gap in existing technologies lacking dynamic feedback. It possesses the following advantages:

[0024] (1) Modular design: This utility model supports segmented maintenance. Replacing a single cable only requires disassembling a partial unit, which improves maintenance efficiency by 70%.

[0025] (2) Dynamic adjustment: The cable tray and U-shaped elastic clip of this utility model work together to achieve elastic binding of cable tubes, adapt to different cable sizes, and the pressure sensor avoids damage from excessive tightness, thus extending the cable life.

[0026] (3) Environmental adaptability: The anti-corrosion coating and damping pad design of this utility model enable the device to have a service life of more than 15 years in salt spray and vibration environments;

[0027] (4) Cost advantage: Compared with the traditional grouting scheme, the overall maintenance cost of this utility model is reduced by 60%. Attached Figure Description

It is quickly fitted onto the cable duct through a quick-release flange to form a continuous fixed structure.

[0048] Secure the cable conduit inside the cable fastening box using the cable laying bracket. Adjust the opening and closing of the U-shaped clamp to keep the pressure sensor reading within a safe threshold (≤0.5MPa) to avoid damaging the surface of the cable conduit.

[0049] On the other hand, the cable condition can be checked regularly through a transparent viewing window, and when replacement is needed, only the corresponding unit needs to be removed without damaging the overall conduit.
